Abstract: Safety conduit system includes a pair of couplings, each including an elongate fitting or housing having barbs at one end and spaced apart teeth at an opposite end. A conduit made of a thermoplastic hose, and stainless steel reinforcement around the hose is attached at each end to the barbed end of a respective coupling. A thread is optionally provided on an outer surface of the housing inward of the barbs so that ferrules on the conduit and having inner threads can threadingly engage with the threads on the couplings and enable the safety conduit system to maintain connection between the conduit and couplings at relatively high fluid flow pressure through the safety conduit system, such as around 40,000 psi.

Abstract: A fluid delivery system having a safety system with interchangeable parts. Also a safety system having a conduit specifically designed to withstand ultra high-pressure fluids exceeding 24,000 psi.

Abstract: A fluid delivery system having a safety system with a breakaway component. Breakaway component further comprising an internal tube that also has breakaway capacity to prevent leaks before breakaway. Also a break away system have a turbulence coil within the break away portion of the conduit to enhance the protection provided by the safety system.

Abstract: A housing at each end of a conduit defines a valve seat. A connector is connected to a valve body in each housing and holds the bodies away from the seats until the conduit fails, after which each body moves into contact with the corresponding seat. A compression zone between each body and the corresponding seat is sufficiently large to reduce heat generated thereat from adiabatic compression of the fluid flowing therethrough. In a variation, two heat-dissipating ribs are externally positioned on each housing adjacent the compression zone. In another variation, the connector is a generally helical spring within the conduit and sized to be in contact with an interior wall of the conduit so that the spring provides structural strength thereto. In another variation, a third housing is employed as a one-way check valve.

Abstract: There is disclosed a three bolt breakaway coupling adapted to be connected to either one or both ends of a flexible fluid conduit having a housing at each end that may include a valve. The breakaway coupling has two generally triangular shaped flanges where each flange has a central opening surrounded by a sealing member such as an 0 ring and an opening located at each corner of each triangular shaped flange for receiving a shear bolt. At least two of the three shear bolts which couple the two triangular flanges together will break when a specified pull at any angle is applied to the three bolt breakaway coupling. The first and second housings may contain valves for controlling the flow of a fluid through the conduit.

Abstract: In an embodiment, there is disclosed a flexible fluid conduit having a breakaway coupling at one or both ends and a safety system that includes a spring in compression which applies thrust (a pull) to flapper valves at both ends of the flexible fluid conduit through relatively stiff bendable spring rods which push the valves open as long as the flexible hose is intact. Upon a hose failure such as a drive away, a coupling separation, a hose separation, or a longitudinal tear, the spring looses its compression and the pull applied to the valves by the spring in compression changes to a pull which immediately pulls the valves to close.
